Maduka Metals, a reputable manufacturer and supplier located in Abuja, Nigeria, specializes in high-quality Tool and Die Steel H13 Bars that are engineered for top-notch performance in hot-working applications. These bars are crafted with precision to ensure exceptional toughness, wear resistance, and thermal stability, all while adhering to international standards for industrial tooling. Maduka Metals serves a diverse array of industries, including automotive, aerospace, die-casting, and manufacturing, providing reliable and durable steel solutions. Thanks to advanced heat treatment processes and rigorous quality control, each Tool and Die Steel H13 Bar boasts superior hardness, dimensional stability, and a long service life, making them perfect for demanding tool and die applications.
The composition of Tool and Die Steel H13 Bars includes carbon (0.4%), chromium (5.0%), molybdenum (1.3%), vanadium (1.0%), and silicon (1.0%), along with trace amounts of manganese. This blend results in an impressive mix of toughness, hardness, and heat resistance. Mechanically, H13 steel shows a tensile strength of around 1100–1300 MPa in its annealed state and can achieve a hardness of 50–55 HRC after heat treatment. It maintains its shape even at high temperatures and offers remarkable resistance to thermal fatigue, making it an excellent choice for hot-work tooling.

When choosing Tool and Die Steel H13 bars, consider factors such as hardness, heat resistance, wear resistance, toughness, machinability, and the specific requirements of the application, including temperature and load conditions.
Tool and Die Steel H13 bars offer limited corrosion resistance due to their high alloy content, but they can still be susceptible to rusting in harsh environments. To improve corrosion resistance, they may require additional surface treatments like coating or regular maintenance to prevent degradation.
Tool and Die Steel H13 Bars are widely utilized in industries that demand tooling capable of enduring extreme heat and stress. They are perfect for creating die-casting dies, extrusion dies, forging dies, and hot shear blades. In the automotive and aerospace fields, H13 Bars are employed for components that face high-temperature operations, such as molds and tooling for engine parts. Moreover, these bars are also suitable for heat-treating equipment, industrial machinery components, and other applications that require materials that are tough, wear-resistant, and thermally stable.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
